That puts you at an extreme disadvantage which could be solved with ... money. And of course in history guerillas often have had sources of supply from other countries who are in effect providing the money. All the proxy wars of the Cold War period were like this - the Chinese or Russians or North Koreans supplying guerillas in Africa against non-communist governments or the US or South Africa doing the same for guerillas against "communist" governments.

I'm from Zimbabwe - everything in Rhodesia was about money. Money needed by the government of the time to stop the guerillas and money needed by the guerillas to house them in neighboring countries, feed and arm them.

Now that Zimbabwe is in terrible economic trouble and has obviously rigged elections and much suppression of opposition voters and of course a military coup that everyone denies was a coup, there is no rebellion and there are no guerillas because they would have no support (no money, no safe harbour, no weapons). The Russians, Chinese, South Africans and DPRK have the situation they want and the US etc don't care about it either.
